My love is pizza shaped. Won’t you have a slice? It’s circular, so there’s enough to go around.

O ye of little faith, who believe that somehow the birth of Christ is dependent upon acknowledgment in a circular from OfficeMax!
Thoughts are circular, they don't take you anywhere. They don't have feet-they can't gain any ground. They can trap you if you don't eventually stand up and make a move.
I started thinking about little kids putting a cylindrical peg through a circular hole, and how they do it over and over again for months when they figure it out, and how basketball was basically just a slightly more aerobic version of that same exercise.
Love is a circular emotion that surrounds you, like a hug. Or a noose.
